Ultimaker 2 heated bed error

Recommended Posts

Hi All,

 

My UM2 heated bed has stopped working. It constantly says its 27C if i manually heat it up it wont go any higher.

 

I have:

resoldered the 4 pins to the heated bed - they all looked ok tbh though

Checked the board connections - no issues there.

 

I have checked the current running through the board to the heater no issue and also the current at the heated bed end and im getting a readout on all the pins so cant see an issue there.

 

I havent been rough with the machine at all, could it just be the heated bed has died? The printer has been running close to 10k hours.

Sorry, I haven't logged on in a couple days. 832 sounds way off. Here are the points to measure:

 

 

 

Oh no that wasnt a dig at you, i just remember a year or so ago you would get 5 replies to  question like this.

 

So i have a sneaking suspicion im using my multimeter wrong for measuring resistance. I will take a look at a guide.

That's a bit weird. It could be that the connection on the bed plate has gone out. To make sure I'm not missing any steps:

* When trying to heat, the button rotations are showing on the screen that temperature is being set (even though it's not reaching that temperature)?

* Is it giving you any sort of error message when you try to heat and it fails?

* Is there any sign that your Bed Heater Cable has the insulation caught in the green terminal block on the electronics board?

* Can you confirm that the Heater 2 and Temp 2 connections on the board are all empty?

* How long have you had your printer?

Answering your questions in order:

 

1.) The printer will start its warm up to get ready to print, but will never actually print as the bed isnt warming up. So i manually decided to see if i can change the bed temp. I can set it to higher but it will never get higher then a reading of 25-28 which seems a bit off anyway.

2.)No error

3.)No i think that all looks fine, at the weekend i can remove reseat the cables on the board

4.)yes

5.)Oh a long time, its a real work horse (it has been used for thousands of hours)
